Given that gcc can be a bit heavy, it would be neat if we had a compile farm somewhere made out of Qemu images with overlays that people working on XOs could shell into in order to compile various software. I use this approach on my workstation when I want to do something that's messy (e.g. installing large-ish packages from yum, or building documentation sets). Mostly it would be a sysadmin-level problem, managing accounts, watching for security issues, that kind of thing. Ah well, another thing on the "if I had time" pile.
